"We learned on January 31 that Barnes & Noble had suffered a major setback in a patent-infringement lawsuit filed against the company by Microsoft. That day, an administrative law judge at the International Trade Commission had tossed out the company's key defense, that Microsoft was engaging in 'patent misuse' as part of a larger scheme to 'kill Android'. Today the full opinion has been made public." Microsoft's protection racket might be legal, but that doesn't make it moral. It's based on software patents, and is thus, by definition, morally reprehensible and sleazy.

Very interesting part from there: (B&N talking about how MS trolls initially approached them about this):

“And what they basically told us was, it doesn’t matter if you have defenses, whether you don’t infringe, whether our patents are invalid, you’re going to need to take a license, because there’s no way that you can get out of our grasp, that we have so many patents that we could overwhelm you.”
